Some chimp, and another animal (5)
I believe the answer is:
panda
'animal' is the definition.
(I've seen this before)
'some chimp and another' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'PANDA' can be found hidden inside 'chimp and another'.
(Other definitions for panda that I've seen before include "Racoon-like animal" , "Black-eyed animal" , "Bearlike animal" , "One bearlike" , "Raccoon-like animal" .)
